Method Inventory


method %GetNext(Output key, Output value) as %Boolean [ Language = objectscript ]
%GetNext() advances the iterator and returns true if the iterator is positioned on a valid element, false if it is beyond the last element. The key for the element is returned in the first output argument and the value in the second. To call this method, pass the key and value arguments by reference to receive their return values. To iterate over a %DynamicArray, use the following pattern:
while iterator.%GetNext(.key,.value) {
// key and value now contain the key for the element and value contains the value.
